Analysis

Colin Fray, BBC Radio Nottingham's Forest correspondent

If you are spending the sort of money Forest are spending, you would expect quality from the players you are bringing in as a given - so let's assume that will be the case.

For me the important thing about these signings is the message it sends out. It answers a question fans have been asking since Evangelos Marinakis took over: 'How much money is he prepared to spend to really have a go at bankrolling Forest into the Premier League?'

A deal this size at Championship level would suggest he is very serious about getting Forest into the top flight. He is also serious, maybe, about doing it this season. Forest are not prepared, it seems, to have another season of consolidation.

Instead they are prepared to have a right go, spending the kind of money that Wolves did last season - we all saw the benefits and they will be playing in the Premier League next season.
